PINPOINT TEST G426404p11 : DTC B2833: SENSOR POWER SUPPLY CIRCUIT TESTS

G426404t47 : CHECK THE SENSOR POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT
1. Disconnect the battery negative terminal.
2. Disconnect the evaporator sensor connector, RA10.
3. Disconnect the rear climate control module connector, RA01.
4. Measure the resistance between RA01, pin 09 (G) and RA10, pin 01 (G).

- Is the resistance greater than 5 ohms?

-> YES
REPAIR the high resistance circuit. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G426404t48.

G426404t48 : CHECK THE SENSOR POWER SUPPLY CIRCUIT FOR SHORT CIRCUIT TO GROUND
1. Measure the resistance between RA10, pin 01 (G) and GROUND.

- Is the resistance less than 10,000 ohms?

-> YES
REPAIR the short circuit. TEST the system for normal operation.

-> NO
GO to Pinpoint Test G426404t49.

G426404t49 : CHECK THE SENSOR POWER SUPPLY CIRCUIT FOR SHORT CIRCUIT TO B+
1. Reconnect the battery negative terminal.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between RA10, pin 01 (G) and GROUND.

- Is the voltage greater than 3 volts?

-> YES
REPAIR the short circuit. TEST the system for normal operation.

-> NO
INSTALL a new evaporator sensor. TEST the system for normal operation.
